Greddy Type R BOV
Anyone know if the Greddy Type R BOV can be run in a system that sees less than 10PSI of boost? An online store says that the Type S is good up to 18PSI and the Type R is good for 12PSI and up.

i believe he wants to use it as a diverter isntead of a blow off valve. the greddy can be fitted with an adapter so you can plumb the exhaust of the valve back to your intake rather than just venting to atmosphere. another brand would work as well if it had that capability, but i don't know of any off the top of myhead.
there has to be a way to run it with less than the 12lbs of boost right? i mean if you went with a nice sized turbo, say a t04/60-1 you could make pretty nice hp numbers running just 10lbs, and ,of the 2 greddy bov's (the type-r and type-s), the type-s would probably be smaller than you would want with a turbo pushing that much air.
just helping to clarify

There are two different type R BOV part numbers. One with the standard spring and one with the stiff spring for high boost applications. I just had a heck of a time getting the type R with the standard spring...
BTW the Type R is physically much bigger than the Type S, but still doesn't weigh anything to speak of.

The stiff spring is used for more than 18PSI of boost. The normal spring only says 12PSI+. I'm trying to find out whether it can be used for applications running less than 12PSI. BTW BingoBoy is right, I want to use it as a diverter valve redirecting the air back into my intake system and the Greddy BOV can be used in this manner.

It's overkill for anything short of running 15psi or less.
If you're going to insist on using it (for under 15psi), get the "std." spring.
You cannot use the "stiff" spring, cause it will not open unless it's over 20psi!

just from screwing around with the one I have (not on car), it opens pretty dag easy with the spring loostened all the way, and a little bit of vacume help. I would be really suprised if just a couple psi didn't make it open.
but still, I'm not sure, and would love for someone to clear it up a little....
"will the Type R open with 10PSI?" .... or less?
